seed core [′sēd ‚kȯr]
(nucleonics)
A reactor core that includes a relatively small volume of highly enriched uranium, surrounded by a much larger volume of natural uranium or thorium in a blanket; as a result of fission in the seed uranium, neutrons are supplied to the blanket, which is made to furnish a substantial fraction of the core power. Also known as spiked core.

The centerpiece of the production system is a proprietary ion implantation machine called a Xenator, which embeds Xenon-124 atoms, into the ceramic seed core of the seed.
The I-Plant(TM) seed is produced at Implant Sciences' 39,300 square-foot facility, located in Wakefield, MA, where the seed cores are ion implanted with non-radioactive Xenon-124 gas, which can be safely inventoried in large quantities.
After the seed cores are ion-implanted with a non-radioactive gas, they can be safely inventoried in large quantities as needed.
